Symptoms

  • NVDIMM 僅限儲存裝置的部署失敗,並傳回以下錯誤。

#<ASM::Provider::Elementmanager::Scaleio::WrappedRestClientException: {"message"=>"Error with details", "httpStatusCode"=>500, "errorCode"=>0, "details"=>[{"errorMessage"=>"Could not open SDS device", "error"=>"TGT_ADD_DEV_OPEN_ERROR", "rc"=>71, "info"=>[{"type"=>"EET_ACC_DEV_KEY", "objId"=>nil, "str"=>nil, "num"=>nil, "mdmKey"=>nil, "protectionDomainKey"=>nil, "storagePoolKey"=>nil, "accelerationPoolKey"=>nil, "sdsKey"=>nil, "deviceKey"=>{"id"=>"cd4f0e1f00050000", "sdsKey"=>{"id"=>"d760414200000005", "name"=>"Sds-001.powerflex.com", "hostname"=>nil, "port"=>nil}, "path"=>"/dev/dax3.0", "name"=>"/dev/dax3.0"}, "volumeKey"=>nil}]}]}>

 

  • 嘗試在 PowerFlex 中將 dax 裝置新增為加速裝置,則會導致出現錯誤訊息「無法開啟 SDS 裝置」。
[root@flex002 ~]# scli --add_sds_device --sds_name Sds-001.powerflex.com --device_path /dev/dax3.0 --device_name /dev/dax3.0 --acceleration_pool_name AP-1 --force_device_takeover
Error: MDM failed command.

  • 重新啟動儲存節點後,在 PowerFlex 中將 dax 裝置新增為加速裝置會成功。

Cause

  • 設定 NVDIMM 裝置後,必須先在僅限儲存節點上重新開機,才能將其新增為加速裝置至 PowerFlex 加速集區。這是 PowerFlex 3.6 中推出的新問題。
  • 自今日起,PowerFlex Manager 不會在其自動化中執行此重新開機。因此,使用 NVDIMM 裝置的僅儲存服務部署會失敗。

Resolution

注意:此問題已在 PowerFlex 4.X 中修正。

PowerFlex Manager 會設定 NVDIMM DAX 裝置,然後一次將它們新增至 PowerFlex 節點。

由於此問題,當 PowerFlex Manager 嘗試為第一個節點新增 dax 裝置時,僅限儲存的服務部署會失敗。其餘節點將不會設定其 dax 裝置。

因應措施是手動執行 PowerFlex Manager 指令檔,在服務中的所有 SO 節點上設定 dax 裝置,然後為每個節點重新開機。

階:

# Copy dax config script from PFxM Appliance to SO node 
#SSH to PFxM and run the following command to copy the script from PFxM to the SO node scp /opt/asm-deployer/scripts/configure_ndctl_namespaces.py root@SO_NODE_IP:/tmp

Ex.
scp /opt/asm-deployer/scripts/configure_ndctl_namespaces.py root@10.20.30.15:/tmp # Connect via SSH to the SO node and run dax config script that was copied from PFxM to the SO node
cd /tmp python configure_ndctl_namespaces.py 4 # where 4 is number of nvdimms on node # Reboot SO node shutdown -r now
在 PowerFlex Manager 中重試服務部署。
